While in shell mode, you can type any cell management tool command
at the
cmt> prompt, as shown in this example.

cmt>cell -husage: cell [options]
-a,--application-states display the state of each application
on the cell [DEPRECATED - use the
cell-application command instead]
-h,--help print this message
-i,--pid <arg> the process id of the cell [REQUIRED
if username is not specified]
-m,--maintenance <arg> gracefully enter maintenance mode on
the cell
-p,--password <arg> administrator password [OPTIONAL]
-q,--quiesce <arg> quiesce activity on the cell
-s,--shutdown gracefully shutdown the cell
-t,--status display activity on the cell
-tt,--status-verbose display a verbose description of
activity on the cell
-u,--username <arg> administrator username [REQUIRED if
pid is not specified]
Note: You will be prompted for administrator password if not entered in command
line.
cmt>

The command returns to the
cmt> prompt when it finishes executing.
To exit shell mode, type
exit at the
cmt> prompt.

Use the cell command of the cell management tool to suspend the task scheduler so that new tasks cannot be started, to check the status of active tasks, to control cell maintenance mode, and to shut down the cell gracefully.

vCloud Director uses the Quartz job scheduler to co-ordinate asynchronous operations (jobs) running on the system. If the Quartz scheduler database becomes corrupted, you might not be able to quiesce the system successfully. Use the fix-scheduler-data command of the cell management tool to scan the database for corrupt scheduler data and repair that data as needed.

Use the fail-tasks command of the cell management tool to update the completion status associated with tasks that were running when the cell was deliberately shut down. You cannot use the fail-tasks command unless all cells have been shut down.

Use the reconfigure-database command of the cell management tool to update connection properties for the vCloud Director database. This command cannot be used to change the database type or migrate data to another database instance.
